Saratoga, Calif., March 3, 2008 - Library Technologies, Inc. (LTI) and
Plato Networks, Inc., a fabless communications semiconductor company, announced the successful use of LTI's YieldOpt tool for analyzing
the impact of process variation. Modeling process variation has emerged as a formidable
challenge at small geometries with tens of global, systematic and random on chip variation sources for each device type. Traditionally, such analysis has been done using corners, where a ring oscillator is simulated using Monte Carlo
techniques to find the delay distribution and associated process condition
for a certain deviation from the mean value. This becomes impractical as the
number of variation sources and devices affected by
variation increases. An alternative is statistical library characterization
using sensitivities process parameter variation. This also
becomes impractical when random on chip variations need to be
accounted for.

"YieldOpt has a fast direct approach to process variation which is more
exhaustive than Monte Carlo analysis but at a very small fraction of the
cost and time," said Mehmet Cirit, president of Library Technologies,
Inc., "it can be used across all standard, custom core and IO cells to reduce
pessimism and avoid optimism during timing analysis, covering variation
of both passive and active devices. It handles intra-chip as well as on chip random variations and mismatches."

YieldOpt interfaces to LTI's SolutionWare characterization and modeling tools. Once enabled, best case and worst case timing and process conditions for each cell are automatically identified by YieldOpt.
Alternatively, it interfaces into a traditional timing analysis flow, without the need for any special tools like statistical static timing analyzers(SSTA).

"LTI's YieldOpt saved us significant time in identifying the
correct process conditions for our mixed signal designs. It also
allowed the use of a more relevant test bench," said Wiren Perera, vice president, marketing and business development at Plato Networks.
